What all do I need to claim my son as a dependent on my taxes ?

Make sure you have entered your child as a dependent in My Info, and that you have entered the child's Social Security number.    Careful— do not say that your child’s SSN is not valid for employment.  If your child was born in 2022 make sure you said he lived with you the whole year.  There is an oddly worded question that asks if the child paid over half their own support.  Say NO to that question.

Then continue on to enter your income.  If you had income earned from working in 2022 you may be eligible for child related credits.  Without any income you will not be eligible for a refund.

If the dependent:

Is under the age of 19 on Dec 31 of the tax year and;

Did not provide more than 50% of their own support and;

Lived with you for more than 182 days during the tax year;

*******************OR*******************

Is under the age of 24 on Dec 31 of the tax year and:

Is enrolled in an undergraduate program at an accredited institution and:

Is enrolled as a full time student for any one academic semester that begins during the tax year, (each institution has their own definition of a full time student) and:

the STUDENT did NOT provide more that 50% of the STUDENT’S support (schollarships/grants received by the student ***do not count*** as the student providing their own support)

Then:

The parents qualify to claim the student as a dependent on the parent's tax return . Period, End of Story. It "does" "not" "matter" how much money the dependent earned during the tax year if "all" of the above requirements are met.
